Adding a delegate host through an SSH connection

To succeed, the following statements about the login account used to perform this procedure must be true:
  • The account exists on both the master host and on the delegate host.
  • The account has serviced CLI privileges.
  • The account has either public key authentication or password authentication enabled on the master host and on the delegate host.
Use this procedure to add a delegate host to a resource pool through an SSH connection. Repeat this procedure on each delegate in your Resource Manager deployment.
  1. Gain access to the Control Center host, through the console interface of your hypervisor, or through a remote shell utility such as PuTTY.
  2. Start a command-line session as root.
    1. In the Appliance Administration menu, select Root Shell.
    2. Select Run, and then press Enter.
    The menu is replaced by a command prompt similar to the following example:
    [root@hostname ~]#
  3. Add a delegate host to a resource pool.
    If the master and delegate host are configured for key-based access, the following command does not prompt you to add the delegate to the list of known hosts or to provide the password of the remote user account.
    Use the hostname or IP address to identify a Control Center host. If you use a hostname, all Control Center hosts must be able to resolve it, either through an entry in /etc/hosts or through a nameserver on the network. In the following example, replace Hostname-Or-IP with the hostname or IP address of a delegate host, and replace Resource-Pool with the name of a resource pool.

    If the host is behind a router or firewall for network address translation (NAT), include the option --nat-address to specify the NAT device's hostname or IP address and port of the delegate host.

    serviced host add --register Hostname-Or-IP:4979 Resource-Pool \
      --nat-address==NAT-Hostname-Or-IP:NAT-Port
